Another Update from Scotland -- Getting caught in the protests

Another phone update from John. He hasn't been able to blog because for the past hour or so he was stuck in a crowd surrounded by riot police. AP has a story on the "riots."

John told me that not only was the whole crowd -- which was quite a mix of folks including media, tourists and people from Edinburgh -- not allowed to move, they were all basically detained. And, before they could leave, everyone had their photo taken by the police. Not like a group shot. Before anyone could leave the penned in area, they went through a line to have a picture snapped.

Sounds crazy. Hopefully, John will have computer access soon and he can give more details. But one question: is this legal in Great Britain?
